A dissection of fingerprint fuzzy vault schemes
Vedrana Krivokuća, Waleed Habib Abdulla, Akshya Kumar Swain · 2012
The fuzzy vault construction is one of the most widely adopted approaches for the protection of fingerprint data. The popularity of this scheme stems from its ability to deal with unordered sets of fingerprint features, as well as its tolerance to missing or spurious feature elements across multiple acquisitions of the same fingerprint. While a considerable number of fingerprint-based fuzzy vault implementations have been reported in the literature, a review of these schemes does not yet exist, to the best of the authors' knowledge. This paper, therefore, dissects existing fingerprint fuzzy vault schemes and provides a comprehensive discussion of what fingerprint features have been used, and how the locking and unlocking processes have been adapted to suit the nature of the fingerprint features employed.
